MORTON G. BUNNELL, OF CHICAGO, ILLINOIS, ASSIGNOR TO FREDERICK C.AUSTIN, OF SAME PLACE.

DRAG-SGRAPER.

SPECIFICATION forming part Of Letters Patent NO. 593,270, dated November9, 1897.

Application filed March 11, 1897. Serial No. 626,958. (No model.)

To all whom it may concern.-

Be it known that I, MonToN G. BUNNELL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Drag-Scrapers, of

Which the following is a specification.

My invention rela-tes to a construction of drag scraper involving ascoop Which` is adapted to rest upon and to be drawn along the groundand which is provided With a draft attachment to Which a horse or teamcan be hitched, and also provided With handles Whereby it can bemanipulated by and at the Will of an attendant.

Prior to my invention drag-scrapers of such kind have been provided Withrocker-shaped Wear plates or strips attached to the under side of thescoop, and they have also been provided With rockershaped runnersattached to the under side of the scoops and adapted to run upon theground.

In a drag-scraper characterized by my invention the bottom of the scoopis protected from wear by a curved metal plate Which is arranged andadapted to form both a Wearplate and rocker and provided with aplurality of parallel and longitudinally-disposed fins or blades Whichdiminish or taper in Width toward their forward ends and Which areadapted to penetrate the soil, so as to prevent lateral shift or slew ofthe scoop during use and at the same time permit the rocker -shapedwear-plate to rest upon the ground. By such arrangement the combinedWear and rocker plate can also be readily and economically made andprovided With the fins or blades, and after having been thus made it canbe readily and securely applied and secured to the scoop.

In the accompanying drawings, Figure l is a perspective view of adrag-scraper embodying my invention, the scoop being inverted so as toexpose my improved attachment. Fig. 2 is a bottom plan of my improvedattachment cast in one piece. Fig. 3 is an edge view of the same. Fig. ais a section on line w rw in Fig. 2. Fig. 5 is a section on line ma: inFig. 2. Fig. 6 is a plan view of the attachment With the iins or bladesmade separately from the Wear and rocker plate and secured thereto. Fig.'7 is a section on line y y in Fig. 6. Fig. 8 is a section on line .e zin Fig. 6. Fig. 9 is a section corresponding with Fig. 4, butillustrating the rocker-plate stamped up so as to form the blades orfins. Fig. 10 is a section on line z' z' in Fig. 9.

The scoop Ais usually formed bysuitably stamping or striking up asheet-metal blank and is provided With suitably-attached handles B B anda swinging draft attachment C.

The Combined Wear and rocker plate D is of metal and is formed With amarginal fl'ange d, adapted to fit against the under side of the bottomof the scoop and suitably perforated to receive rivet-s, Which aredesirably em- 'ployed as a means for Securing the plate to the scoop.The main portion d' of this plate is formed so as to gradually swell orincline on a curve from its forward end, Which is nearest the front edgeof the scoop, to a point near its rear end and to then recede on a curveto its rear end, as clearly illustrated in several of the figures of thedrawings. By reason of such conformation the forward edge of the scoopWill normally lie in position for scraping up the soil, but bydepressing the handles the forward end of the scoop can be readilytilted up, the ourved orbulgin g Wearplate constituting in such case afulcrum or rocker. This plate covers the greater portion of the underside of the scoop, and While protecting the same from Wear alsomaterially st-ifiens and strengthens the same.

The combined Wear and rocker plate is provided With two ormore-preferably a couple-- parallel blades or fins E, Which are arrangedlongitudinally along the under side of said plate--that is to say, theyextend from front to rear relatively to the scoop. These fins or bladesE are in planes perpendicular or substantially so to the bottom of thesooop, and while projecting downwardly from the under side of the Wearand rocker plate have their edges formed in general correspondence withthe longitudinal curvature of the latter--that is to say, the fin orblade tapers or decreases in width from a point near its rear end towardboth its forward end, and preferably it also decreases in Width fromsaid point toward its rear end. These blades are adapted to cut into thesoil, and hence While guid- IOO ing the scoop and preventing it fromslewing around they will permit the Wear and rocker plate to rest uponthe ground.

As a preferred arrangement and matter of further and special improvementthe Wear and rocker plate can be cast with the blades E, as illustratedby Figs. 2 to 5, inclusive. In this Way a suitably strong plate can beeconomically provided. The blades can, however, be made yseparate fromthe plate and formed with flanges e, as in Figs. 6, 7, and 8, inWhichcase the flanges can be perforated for rivets and snitably rivetedto thewear and rocker plate, as in said figures.

As another way, the Wear and rocker plate can be made of sheet metal andcan be struck up with blades E, as in Figs. 9 and 10, in which case thesides of the blades Will be somewhat inclined. I prefer, however, tocast the wear and rocker plate With the blades. In each arrangement,however, I contemplate forming the blades so that they Will cut into thesoil and permit the wear and rocker plate to rest thereon.

What I claim as my invention is- 1. A drag-scraper comprising a scoophaving a rocker-shaped Wear-plate secured to its under side and providedWith lon gitudinallyarranged blades adapted to penetrate the soil andpermit the wear and rocker plate to rest thereon, substantially asdescribed.

2. A drag-scraper comprising a scoop having a rocker-shaped Wear-platesecured to its under side and provided with lon gitudinallyarrangedblades, which taper in width toward their forward ends, and which areadapted to penetrate the soil and permit the wear and rocker plate torest thereon, substantially as described.

3. A drag-scraper comprising a scoop having a rocker-shaped wear-platesecured to its under side and provided With longitudinallyarrangedblades integral with said plate and made to taper toward their forwardends, the blades being adapted to penetrate the soil and permit the wearand rocker plate to rest thereon, substantially as described.

4. A drag-scraper comprising a sheet-metal scoop, and a cast-metal wearand rocker plate secured to the under side of the scoop and cast withlongitudinally-arranged blades adapted to penetrate the soil and permitthe wear and rocker plate to rest thereon, substantially as described.
